2 Claims. (Cl. 155-51) This invention pertainsto seat supports and more particularly to seat supports used on various types of farm implements and machinery.

The primary object'of my invention is to provide a seat support of improved design and con struction that will efficiently absorb all shocks that the vehicle may be subjected to. A further object is to provide such a seat support of extreme simplicity in design that will be both eflicient in operation and inexpensive to construct and is a distinct iinprovement in the art.

Other objects, advantages and features of the invention may appear from the detailed de scription, the appended claims and the accompanying drawing in which:

Fig. 1 is aside elevation of my invention.

Fig. 2 is a plan View of the same.

Fig. 3 is a perspective viewof the base plate.

Fig. 4 is a sectional view of the block and base plate, showing another. manner of attaching the same. g

Referring to the drawing more particularly, in which similar characters designate corresponding parts, my invention comprises a base plate 10 having suitable holes 11 therein whereby the same is securely fastened to the chassis 12 of the vehicle upon which the improved support is n to be mounted. One end of the said plate 10 is formed into hinge loops 13. A bar 14 having the seat 15 secured at its upper end is hingedly connected to the base plate 10 by a loop 16 at its lower end, said loop corresponding with the loops of the base plate. A pivot pin 17 engages the loops 13 and 16 and is held in position by a cotter pin 18. This provides a hinge like connection for the seat bar 14 allowing the same to have free motion vertically. The said bar is made from a length of spring steel, rectangular liptical curve 14a having'a horizontal portion 14b and a depending end 140 on which'the loop 16 forward. The said member being secured to the base'plate 10 adjacent the end opposite the loops 13 and adapted to straddle the bar 14.

In Fig. 4, another manner of attaching the base plate and block 19 is shown. .In this figure bar and a ;U-shaped member straddling said bar in cross-section and is formed'into a partial elprovided to prevent the seat from tilting too'far the base plate 10 is attached to the chassis, 12 by bolts 22 and the block 19, is" attached to the base plate by small bolts 20'.

It is believed from the description heretofore given of the present invention taken in connection with the drawing that it is entirely clear, the manner in which the seat and the seat supporting means may be mounted on the vehicle.

While I have shown the preferred embodiment of my invention it is understoodthat minor changes in the details of construction may be resorted to within the scope of what is claimed.

'1. A seat supporting bar of spring steel angularly disposedtoward the vehicle to which it is attached having a horizontal portion formed near the lower end'with a loop depending there- 7 from at right angles thereto, a base plate having' loops formed on one end to correspond with the loop of the seat bar, a pin fitted into the said loops forming a hinge like connection, and means to retain said pin in position in the loops, means to secure the said plate on the vehicle, a block of resilient material between the horizontal portion of the seat, bar and the base plate to which it is secured, and a U-shaped member secured to the base, extending upwards over the seat bar preventing the same from tilting too far forward.

2. A spring seat for vehicles comprising a'base plate; a spring bar angularly disposed towards the vehicle towhich'it is attached having its lower end. pivotally attached to said base plate, said barhaving a horizontal portion near its lower end, a block of resilient material disposed between saidbase plate and the horizontal portion of said and attached to-said base plate for limiting the upward movement of said bar.
